Answer:
He needs 5x+56 ft
Step-by-step explanation:
To find how much of fencing he needs , we find the perimeter of the given figure
All sides are equal in a square
To find perimeter of the square we add all the sides
4 sides we have for the square
one side is x, so perimeter of square = x+x+x+x= 4x
Now we find perimeter of rectangle
Opposite sides of rectangle are equal
Here for rectangle we consider only three sides
because fourth side is common for rectangle and square
So perimeter of the rectangle (with 3 sides) = 28 +x+ 28 = 56+x
Total fencing = perimeter of square + perimeter of rectangle
4x + 56 + x= 5x+56
Answer:
D
Step-by-step explanation:
Given
6x² - 2x + 36 = 5x² + 10x ( subtract 5x² + 10x from both sides )
x² - 12x + 36 = 0 ← in standard form
(x - 6)² = 0 ← in factored form, thus
x - 6 = 0 ⇒ x = 6 → D
Well, first, find-out how fast he was going the first time, by dividing 310 by 5. This gives you 62 mph. Now, divide 403 miles by 62 miles per hour in order to find-out how long it would take him to drive 403 miles, if he is constantly doing 62 mph. Your final answer is six-and-a-half hours.
Answer:
445.5 minutes
or 7 hours 25 minutes 30 seconds
Step-by-step explanation:
We can use ratio's to solve
50 ft^2 495 ft^2
-------------- = ------------
45 minutes x minutes
Using cross products
50x = 45*495
50x=22275
Divide each side by 50
50x/50 = 22275/50
x =445.5
445.5 minutes
If we want to convert to hours and minutes, divide by 60
7 hours is 420 minutes
445.5 -420 = 25.5
7 hours 25 minutes
.5 minutes is 30 seconds
7 hours 25 minutes 30 seconds
